hi!!!
thanx for the reply....
i unintalled .net framework 2 service pack 1 and then tried to install
.net framework 3.5 from microsoft site bt the result is same...
and also when i try to install visual studio 2008 the same error 1603
pops up at the time of installation of .net framework 3.5.....
there was no earlier version of visual studio installed on my system....

how can i send u the entire log file....so that u can help me in a better way?

Sorry to piggy back here, but i have the same problem. I have treid most every "solution" I have founf online but same problem. I get a failure whether I am trying to load VS 2008 (errors at .Net 3.5) or simply trying to load .Net 3.0. I have used the log collection tool from Aaron Stebners site, so I have a cab file, just need to know where to send it.

Please try installing from local source rather than disc drive in order to eliminate potential hardware and media causes.Please remember to mark the replies as answers if they help and unmark them if they provide no help.

expected to contain an assembly manifest.

I'm not entirely sure why you'd run into this though. It might be that the download was corrupt or that there's some corruption in an existing version of .Net. Some users have luck with repairing .Net Framework 2.0 (you can do this from Add/Remove Programs) if they're using XP.

Also, there are lots of additional error messages noting that you can't write to your EventLog, probably because it's run out of space. (If you run eventvwr, you can clear the Application Event Log and then you won't get these additional errors and you might start to see additional useful information in the Event Log.)

Just uninstalled and reinstalled every version of the framework. Everything went smooth up unitl 3.0, where it bailed with the same error. I have cleared the event log. Not sure what to do next.Thanks,Bernie

I think I am giving up. I have tried solutions from folks with the exact same error, and still no luck. Not sure why I keep getting teh BadImageFormatException error time after time. I feel like I have tried everything, shouldn't be this hard especially when it seems as though it is such a popular issue. Oh well, no VS 2008 for me.

Thanks for the help, please let me know if it would be advantageous to send the logs to another forum, or start a new thread.
